Hi Steve! Hey, I just took a look at the ASTM B678 specification and it is
a mirror of the ANSIJ-STD-002A specification (except it is out of date in
terms of revisions). I would recommend using the 002A specification in
preference to the B678 specification.

Hi Al,
What I found is that it's a go, no-go solderabilty test. Here's a summary
of the test:
Test Method B678-86(1993) Standard Test Method for Test Method for
Solderability of Metallic-Coated Products
AMERICAN SOCIETY FOR TESTING AND MATERIALS, West Conshohocken, PA. All
rights reserved.
1. Scope
1.1 This test method provides a procedure for evaluating the solderability
of metallic-coated products and test specimens to assure satisfactory
performance in manufacturing processes requiring soldering with soft
(tin-lead) solder and rosin flux. This test method is applicable only for
testing coatings that are normally readily solderable such as: tin,
tin-lead alloy, silver, and gold.
1.2 This test method is qualitative and broadly applicable. It is easy to
perform and requires only simple equipment. There are other solderability
tests not covered by this test method that are more applicable to specific
situations, yield quantitative results, or both. Several are described in
the literature. This is a "go-no-go" test and does not grade solderability
as excellent, good, fair, etc.
1.3 This standard may involve hazardous materials, operations, and
equipment. This standard does not purport to address all of the safety
problems associated with its use. It is the responsibility of whoever uses
this standard to consult and establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior
to use.
You can get this standard at:

It's only 3-pages long, but they charge $25.00 for it...

Hello Technetters,
I don't have an ASTM spec book available, but I have a print that calls out
ASTM B678, Type 2, Class 2.0, Grade 0.
What is it?
Thanks in advance,
Al
